Conclusions

A filtering framework was designed and implemented for MICO, an open-source CORBA implementation. The model supports all essential as well as extended filter properties. Filter objects are first class full fledged CORBA objects, which are dynamically pluggable. Filtering framework is supported through modifications to an implementation of MICO version 2.3.4 which is compliant with OMG-CORBA 2.2 standard. Tools have also been developed to support the development process.
